Ultimate Guide to Resistors

Introduction Resistors are probably the most common and well known of all electrical components. This guide to precision and power resistors answers all your questions about the four main resistor technologies and their performance. In these pages, you’ll find a...

Using Resistors as Heaters

Power resistors and resistance heaters share many common design considerations. In both products, good thermal design ensures low thermal resistance between the element and the exterior environment. Both must be rugged and reliable. Power resistors are often used in...

Appendix – A Resistor Primer

Resistance Resistance is one of three basic quantities in electrical or electronic circuits: Current is the flow of electrons through a circuit. It is the principle quantity because it does work, and accomplishes the desired results. We measure current in Amperes....
